Ford's flaw is his jealousy of his wife. In some ways he is right to be jealous, because Mistress Ford
Page and his wife suffer from the inability to listen to their daughter Anne. Though Page seems a kinder husband than Ford because he trusts and believes in his wife, the generous basis of this relationship is weakened when each plots against the other to choose the right husband for their daughter. Convinced that they are each right, Mistress Page and Page ignore their daughter's romantic desires, preferring to see her in a financially expedient marriage than one based on love. Finally, they learn their lesson when their daughter elopes and marries the man she loves, and they are able to see how their blindness threatened their daughter's happiness.
Most of the characters spent the whole play trying to demarcate the differences between them. The Host made fun of Evans and Caius, and they plotted to get back at him; Page and his wife selected and rejected various suitors for their daughter's hand; and, most of all, Falstaff was tormented and humiliated. Yet the end brings them all together at a wedding feast--even Falstaff. Much of the play involved separating out any who weren't middle-class or who weren't locals, yet at the end all are drawn together, and to some degree, everyone becomes a middle-class local.
For the first time in Shakespeare's works, kings or soldiers do not solely represent England, which is quite a change. While the "real" people seem to be less bloodthirsty than many of their kings, we still see a relatively ungenerous populace. Englishmen pick on foreigners and make fun of their command of the language; men of higher class try to take advantage of middle-class women; various groups try to humiliate and make fun of others; and practically everyone seems to be plotting against someone else. But by the end, everyone is alive, no wars have been fought, and everyone goes together to celebrate a wedding. Despite the array of potentially serious issues in the English country village, a spirit of goodwill nevertheless finally prevails. Plebian England, like the "merry wives" of the title, is shown to be good-humored and, at the last, surprisingly virtuous. It's a refreshing contrast to bloody kings and scheming royal families.
